javascript - Dynamically changing chart data using Django and Highcharts? -

-

How can I allow a user to change the status of the graph and update it on the page?

For example, allows a user to adjust the size of a graph without having to re-administer it.

I am using high charts in Django, which I thought of doing is this. Send all the data up, and set a default size so that there is something to show. Then a dropdown or some addition that allows the user to increase the size of the graph. When a user selects one of them, I somehow slice the data to increase the size.

Example, the list is sent to L = [1,2,3,4,5,6,7,8,9,10], but the default size is 5. Therefore only L [: 5] has been displayed. The user chooses the size of 6, so it reloads so that El [: 6] is displayed.

Example graph:

example graph

< P below is the code snippet of my class based view. A user searches the reddit user who wants to analyze -> data is collected, fun things are done and all charts are set -> 

  def post (self, requested): ... top_chart_series = Consolidated user data, ready to be parsed in JS. # Currently I'm only sending the default size of the data (top 10 words) # But what I want to do is send all the data and after that it settles in JS. Submit Return (Request, & lt; htmlpage.html & gt;, ... lots of variables, {'top_chart_series': top_chart_series ...}) .... Send to JS # So this is where I I'm a bit confused. # At this point, the page is being loaded and the charts are being installed through JS: # So my question is, how can I allow the user to adjust the size of the graph without reposting it without # ? # I lack the knowledge of JS, so that's probably why I can reach it. Anyway, what I was thinking, once all the data is sent, I first chart a graph with the original size (10 words), and then if the user decides to adjust the data # then I Run the function again (?) With the selected size # Here are JS which I currently use, I have not mentioned anything I described. The variables sent by top-word (targets, titles, categories, data) of the function {// parameters: DNS / EG, top_words ('# top_church', 'top word', '{{top_chart_series.categories | secure}}' Are, '{{top_chart_series.data | safe}}'); Var seriesation = JSON.parse (data); Var categories = JSON Paragraph (categories); (Title: {text: null}, categories: categories}, yAxis: {title: {text: $ {target}} {title: {text: {type: 'bar'}, title: {text: null} XAxis: 'Receivable'}}, Export: {Enabled: False}, Credit: {Enabled: False}, Plot Options: {Bar: {showInLegend: false}}, series: seriesoption});

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository.
